摘要
镍钴锰三元电池与磷酸铁锂电池是当今两大主流锂离子电池,他们均能满足车辆动力系统需求。但两种类型电池具有各自的特点,如镍钴锰三元电池具有更高的能量密度和电压,磷酸铁锂电池具有更长的循环寿命及更优的安全性能。本文通过对两种类型电池分别进行充放电性能对比、循环伏安曲线对比、阻抗对比、倍率性能对比、混合动力脉冲能力特性对比,概括了两种类型电池不同性能特点。
Nickel-cobalt-manganese ternary battery and lithium-iron-phosphate battery are two mainstream lithium-ion batteries,both of which can meet the requirements of the vehicle power system.However,two types of batteries have their characteristics,such as nickel-cobaltmanganese ternary battery with higher energy density and voltage,lithium-iron-phosphate battery with longer cycle life and better safety performance.This paper summarizes the different characteristics of the two types of batteries by comparing the charge-discharge performance,cyclic voltammetry curve,impedance,rate performance,and hybrid pulse power characteristics respectively.
